A long anatomy of an extender-o, stands for the "o" in vagina. The extender part extends to the inner part of the woman-hood and clenses it complete with hair and everything. Available in 6 design-her colors. Hoe.
The act of extending your previous night's bender into the next day. Usually performed after an all night drowning session, when one has had little to no sleep, and has arisen from slumber still mildly intoxicated - and most importantly - before the onset of the inevitable hangover. The bender extender will typically push back the hangover to a later date, which may be more convenient for your life.
Waking up after just 2 hours of sleep and still buzzed from the night before, Andrew filled his mug with booze in order to execute a bender extender.
During sex, a woman "extends" her vagina by placing two fingers in a V shape around the man's penis and gripping tightly. This gives the illusion that the woman's vagina is much tighter.
She was either really tight or giving me the vagina extender. Either way, AWESOME.
